SAMUEL J. FISHER, OF CHICAGO, ILLINOIS VENE TlAN BLIND.

SPECIFICATION forming part of Letters Patent No. 451,924, dated May 12, 1891.

Application filed June 24, 1890. Serial No. 356,591. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL J. FISHER, a subject of the Queen of Great Britain, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Venetian Blinds, of

which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a side elevation, one side being broken out to reveal the parts otherwise concealed. Fig. 2 is an enlarged detail showing the manner of securing the blinds in position. Fig. 3 is an enlarged vertical cross-section. Fig. at is an enlarged detail showing an under side view of a slat and cross-wire. Fig. 5 is a reduced end elevation. Fig. 6 is a detail showing the slot in the support. Fig. 7 is a detail showing a slat of the blind turned at an angle. Fig. 8 is a detail, beinga crosssection through a portion of the slat and guard.

This invention relates to Venetian blinds, and particularly to hangers for such blinds.

The object of this invention is to provide an improved device for securing the blind in place, improved means -for supporting the slats of the blind, and an improved guard for the slats, which I accomplish as illustratedin the drawings and as hereinafter described.

That which I claim as new will be pointed out in the claims.

In the drawings, A represents the head or supporting piece. This piece A is provided with two or more elongated slots 7), through which the heads of thumb-screws a may be passed. The head or supporting piece A is secured in position by passing the elongated slots 1) over the heads of the thumb-screws CL and then turningthe thumb-screws a quarter-turn, thereby rigidly securing the head or supporting piece A in position. Thethumhscrews to may be screwed into any convenient part of the window. The head A is provided with slotted bearing-pieces b.

B represents a number of slats, which compose the blind.

0 represents a slat, from which the other slats B are suspended.

D D represent two chains or cords attached to the opposite sides of the slat 0 near its ends, as shown in Figs. 1 and E E represent chains for supporting the slats B. The chains E are arranged in pairs,

one on each side of the slats,as shown in Fig.

ends wrapped around the side bars of the chain-links, as best shown in Fig. 4'.

G G are two cords, one connected to each side of the upper slat O, as best shown in Fig. 5. H is a cord which passes down through openings h in the slats B and C and is secured at its ends to the lower slat, as best shown at the left in Fig. 1. The chain E is not shown at the left in Fig. 1, as it would conceal the cord H. The cord [-1 passes over pulleys e and over a pulley 7"downward to within convenient reach.

J represents a guard for each slat B. Each guard consists of a piece of sheet metal, which is provided with a slightly-elongated hole j,

through which the cord H passes, and its edges are turned over at It around the wires F. The upper slat C is supported from the support A by means of the chains D. The chains D run over pulleys 0, so that the position of the upper slat C may be adjusted by means of the cords G that is, the upper slat (J may be turned at any angle by pulling upon one of the cords G, and it willremain in that position until again adjusted by pulling the other one of the cords G The slatsBlie flat upon the cross-wires F, which wires are secured to the links of the chain E. WVhenever the upper slat O is tilted or adjusted, the chain E on one side will be raised and the chain E on the opposite side will be lowered, 5

thereby tilting the cross-Wires F and slats B. IVhenever the slats'B are tilted, they will be placed at such an angle that sunlight may pass through the elongated holes h. Inorder to prevent sunlight from passing through these holes 7L at such times, I have provided the guard J, as best shown in Figs. 4, 7, and 8. Whenever the slats B are tilted, the cord H must be free in the slot h; but the guard J The chains E are chains 60 light.

[O B. By using Wires F it is not necessary to have any special form of chains or connecting-pieces E and it is not necessary to join the cross-wires F with the chains E at the time when the chains are being made; but

common chains may be used and the cross- Wires F connected with the corresponding links at any time.

By the use of thumb-screws a and the head or supporting piece A, provided with elon- 2o gated slots for the passage of the heads of the thumb-screws, the blind can be readily and quickly placed in position and as quickly and readily taken down.

Vhat I claim as new, and desire to secure 2 5 by Letters Patent, is'

1. In a Venetian blind, the combination, with a number of slatsB and side chains composed of links, of cross-wires F, said crosswires F consisting of two wires connected near their ends and having their ends wrapped around the side bars of the chain links, substantially as specified.

2. In a Venetian blind, the combination, with tilting slats 13, each having an elongated slot hand an elevating-cord H, passing through said slots, of guards J, each having a hole j, through which the cord H passes, and being arranged to cover a slot h, substantially as specified. v

, 3. In a Venetian blind, the combination, with slats B, having slots h, cord H, and side chains E E, of wires F, attached to the chains E E, and guards J, having slots j and turned edges 7c, substantially as and for the purposes specified.

4. In a Venetian blind, the combination, with the head A, having slots 1), and attaching thumb-screws a, passing through said slots 1), of a slat O, slats B, chains l),attached to slat C, pulleys e, mounted in the head A and supporting said chains D, chains E, attached to slat 0, wires F, attached to said chains E, cord H, and guards J, substantially as specified.
